Air-conditioner for vehicle

Abstract

An air-conditioner for a vehicle may include a casing including an internal space therein, wherein the internal space communicates with an upper outlet formed in a side of the casing, an evaporator and a heating member installed in the casing, a partition wall partitioning a portion of the internal space behind the heating member into an upper space and a lower space, wherein the upper space includes at least a floor duct inlet and the lower space receives the heating member therein to form an upward flowing path which guides air from the heating member toward the upper outlet, a floor duct coupled to the upper space to communicate the at least a floor duct inlet with the outside, and a floor door installed in the casing to selectively open the upper space and/or a flowing path fluid-connecting the evaporator and the heating member to the upper outlet.

What is claimed is: 
     
       1. An air-conditioner for a vehicle, comprising:
 a casing including an upper outlet; 
 an evaporator and a heater core installed, sequentially, in a front portion and a rear portion of the casing; 
 a partition wall partitioning an internal space behind the heater core into an upper space and a lower space; 
 a floor duct coupled to each of opposite sides of the upper space in such a way as to laterally communicate with the upper space, wherein the floor duct includes a front floor duct and a rear floor duct; and 
 a floor door installed in a side space of the partition wall in a flow passage formed among the upper outlet, the upper space, and the lower space, wherein the floor door selectively opens a flowing path fluid-connecting the evaporator and the heating core to the upper space, or to the upper outlet, or to both of the upper space and the upper outlet, and wherein the floor door is in an inlet side of the upper space and in an inlet side of the upper outlet to allow air to flow from the evaporator and the heater core to the upper space or to the upper outlet; and 
 a rear floor door provided between front and rear floor duct inlets in the upper space to open or close the rear floor duct inlet, and wherein the front floor duct communicates with the front floor duct inlet and the rear floor duct communicates with the rear floor duct inlet. 
 
     
     
       2. The air-conditioner as set forth in  claim 1 , wherein
 the lower space is an upward flowing path which guides air upwards from the heater core, and 
 the floor duct is a downward flowing path which guides air downwards from the upper space to the outside of the casing. 
 
     
     
       3. The air-conditioner as set forth in  claim 1 , wherein the floor door includes a dome-shaped floor door. 
     
     
       4. The air-conditioner as set forth in  claim 1 , wherein the rear floor door includes a flat type floor door. 
     
     
       5. An air-conditioner for a vehicle, comprising:
 a casing including an internal space therein, wherein the internal space communicates with an upper outlet formed in the casing; 
 an evaporator and a heating member installed in the casing; 
 a partition wall partitioning a portion of the internal space behind the heating member into an upper space and a lower space, wherein the upper space includes at least a floor duct inlet and the lower space receives the heating member therein to form an upward flowing path which guides air from the heating member toward the upper outlet; 
 a floor duct coupled to the upper space to communicate the at least a floor duct inlet with the outside of the casing; and 
 a floor door installed in an inlet side of the upper space and in an inlet side of the upper outlet in the casing in a flow passage formed among the upper outlet, the upper space, and the lower space; 
 wherein the floor door selectively opens a flowing path fluid-connecting the evaporator and the heating core to the upper space, or to the upper outlet, or to both of the upper space and the upper outlet. 
 
     
     
       6. The air-conditioner as set forth in  claim 5 , wherein the floor door includes a dome-shaped floor door. 
     
     
       7. The air-conditioner as set forth in  claim 5 , wherein the floor duct forms a downward flowing path which guides air downwards from the upper space to the outside of the casing. 
     
     
       8. The air-conditioner as set forth in  claim 5 , wherein the at least a floor duct inlet includes a front floor duct inlet and a rear floor duct inlet and the floor duct includes a front floor duct and a rear floor duct which are integrated with each other, and wherein the front floor duct communicates with the front floor duct inlet and the rear floor duct communicates with the rear floor duct inlet. 
     
     
       9. The air-conditioner as set forth in  claim 8 , wherein a rear floor door is provided in the upper space to selectively open the front floor duct inlet and the rear floor duct inlet. 
     
     
       10. The air-conditioner as set forth in  claim 9 , wherein the rear floor door includes a flat type floor door. 
     
     
       11. The air-conditioner as set forth in  claim 1 , wherein the upper outlet is provided on upper portion of the casing and includes a defrost vent and a face vent. 
     
     
       12. The air-conditioner as set forth in  claim 5 , wherein the upper outlet is provided on upper portion of the casing and includes a defrost vent and a face vent.
